OILER.

vide an oiler ca able of reacliing, either vcrtically or angu arly, to aconsiderable distance beyond the ordinary scope or reach of the oerator, thereb use o ladders and ot 1er contrivances of similar purpose.p

A second object is, to provide such oilers adapted to be used withentire readiness by even inexperienced. persons. Third, to rovide .suchdevices 1n forms economica to manufacture and which shall eifectuallyfulfil their functions.

These and other minor objects are attained b the novel combination andarrangement of7 parts, hereinafter described and shown in theaccompanying drawings, in which:

Figure 1, represents a side elevation of the entire device, a portion ofthe same being broken away in order to show' the interior arrangement.Fig. 2, is a transverse section of the same taken on a line indicated by`operated y means o the piston-ro the characters a-a, of Fig. 1. Fig. 3,is a transverse section of the handletaken on a line indicatedby thecharacters b-b,'of I igl.

The device consists 'of a cylindrical reservoir 1, preferably made froma suitable section of tube, threaded for the cover 2, which is providedat the extreme upper end with a cap 3; the lower end of the tube issimilarly threaded and attached to a light metal frame 4, havingimmediately above the threads a circular-portionprovided with posts 5,which support a similar portion 6, which forms the bottom of the oilchamber.

In the center of the portion 6, is an annular projection 7, to whlchis'tightly iitted a tube 8, forming the chamber o a pump and therein aiston 9; this containin piston is cured in any suitable manner to it;about the rod and within the chamber is disposed an openly wound helicalspring 11, in such manner'as to exert its tension against the lowerSpecification of Letters Patent.

side of the piston keeping it normally extended.

Near the bottom of the pump chamber 8, is an opening 12, provided with aclapper valve 13, the same being so arranged that as the piston asecndsoil is drawn in to the pump chamber through the opening 12, but on thereturn stroke of the piston it is prevented from Howing back into theouter cylinder, but caused to pass through the orifice 14, of thechamber 15, which has connected. therewith the discharge pipe or oilerspout 16, secured as at 17, to the chamber casing, and curved or turneddownward as may be desired at 18, in order that the oil may bedischarged at any given point.

The piston-rod 1() passes freely through the frame 4, and stuffing box19, where it connects with a cord or wire 20.

At the lower part of the frame 4, are secured Y shaped members 21,united in a fer- ,rule 22, which is adapted to receive the hanator inmanipulating the oiler.

The catch is kept in its proper relative position by means of the guidepins 26 and 26', which also limit the movement which may be given to itlaterally.l

In operation the cap is removed and the reservoir filled with oil, orother desired iiuid, and the cap replaced, whereupon the o iler is incondition for operation; a downward pull of the hook catch 25, istransmitted through the cord to the piston-rod and piston, causin thelatter to descend and force any liqui that may be contained in the pumpchamber through the opening 14, and hence through the spout to its4point 18 upon releasing t e hook 25,-it is carried upward by the spring11', which has the effect of raising the piston as well and replenishingor recharging the pump chamber 8 It will be obvious that minor changesmay be made in the design and construction of the oiler withoutdeparting from the spirit of the invention or the scope of the claims.

Having thus described my invention what I clai'm as new and desire tosecure by Letters Patent is:

l. An oiler comprising a reservoir having a discharge pipe7 a pumpcylinder disposed within the reservolr, a 'piston within the pump.cylinder', a clapper valve `arranged at the lower end and in the wallsof the said cylinder7 a frame connecting the cylinder and the reservoirat the lower end thereof, a piston-rod, a stuffing box connected withthe frame, a handle of indeterminate length attached to the frame, anoperating hook and connecting means between said hook and said istonrod, all substantially as shown and escribed.

2. In combination with an oiler comprising acylindrical casing, adischarge ipe connected therewith, a pump within t e casing andoperative means combined therewith, of a frame partly below and withinsaid casing, said frame having a chamber communicat- JOHN E. THRON.
